.. BOTTLE-WASHER.

Specification of Letters Patent. Patented D 9 7, 1920,

Application filed May 29, 1919. Serial No. 300,532.

This invention relates to bottle washing machines especially adapted for use by dairymen who have a relatively small number of bottles to wash, so that the installa tion of a large machine would be undesirable.

; The invention has for its general objects to improve and simplify the construction of machines of thischaracter so as to be reliable and efficient in use, comparatively simple and inexpensive to manufacture, and so designed that they can be easily adapted for either hand or power drive.

A more specific object of the invention is the provision of a double brush spindle machine in which the spindles are movable toward and from each other to throw the friction wheels thereof into and out of engagement with the common friction disk or pulley which may be hand or power driven, there being novel means for throwing the friction wheels into and out of operative position.

With such and other objects in view, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims ap pended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention,

and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 is a side view of the machine;

Fig. 2 is a plan view with portions in sec tion to illustrate the details;

Fig. 3 is a perspective view of the machine;

Fig. 4 is a sectional view on the line 4-4, Fig. 1; and

Fig. 5 is a detail sectional View of the means for holding the friction disk in neutral position when a belt drive is used.

Referring to the drawing, A designates a tank and B the bottle washing machine which is mounted on one wall of the tank.-

The machine comprises a frame 1 whichhas a vertical attaching base portion 2 which is bolted or Otherwise fastened to the tank,

the frame being inclined at about forty degrees to the horizontal. On the frame 1 are ali'ning spaced bearings 3 in which is mounted a spindle 4 which is disposed at the same inclination as the frame and extends into the tank with its lower end provided with a coupling 5 for receiving the shank 6 of a standardbottle washing brush 7.

Mounted on the main frame 1 is a swinging secondary frame 8 hingedly connected by a pintle 9 with hanger brackets 10 on the main frame, and on the secondary frame are spaced alining bearings 11 in which'is rotatably mounted a spindle 4 which is also provided with a bottle scrubbing brush simie lar to the brush 7. A I

The spindles 4 and 4 are provided re-; spectively with friction wheels 13 and 13 at opposite sides of a double face friction disk 14. The friction wheel 13 is always in engagement with the disk 14, and the wheel 13 is held in frictional contact with the said disk by means of a spring 15 which is connected with-the swinging .secondary frame 8 and with the main frame. A throwout device in the form of a lever 16is fulcrumed on the spindle 4 and has a cam surface 17 which bears against the spindle 4, so that when the lever 16 is moved from the dotted to the full-line position, as shown in Fig. 4, the cam 17 moves the spindle 4 away from the spindle 4, so. that the friction wheel 18 will be out of driving engagement with the friction disk and shaft 4 will be only op- When the lever is in the dottederated. line position the spring .15 maintains the. friction wheel 13 'in driving engagement with the friction disk and the shaft 4 will be operated. It will thus be seen that both. shafts or only one shaft can be operated.

The friction disk 14 is mounted on a shaft 17 rotatable in a bearing 18 on the top edge of the frame 1, and for hand drive the shaft has a pinion 19 which meshes with a gear wheel 20 fastened to a shaft 21 which has an operating crank or handle 22, the shaft 21 being journaled in a bearing 23 on the gear casing 24 which has a split hub 25 to fit on the projecting end of the bearing 18, there being a clamp bolt 26 passing through the gears 27 of the split hub, so that the gear casing 24 with the gear and operating handle can be adjusted to any desired position around the shaft 17 as a center.

, If it is desiredto operate the machine ably the crank casing 24 and attached parts is removed and the device shown in Fig. 5 substituted, This constitutes a cap 28 clamped on the bearing 18 and having a spring-pressed follower 29 which engages the end of the shaft 17 so as to move the shaft and friction wheel to a neutral'position when the transmission mechanism is opened by throwing the lever 16 from the dotted to the full-line position, thus permittingthe friction disk to rotate free from the friction wheels and thus permit the brushes to remain idle while the pulley or friction disk still rotates. This does away with the necessity of a fixed and loose pulley. From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the artto which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired asfall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Lettels Patent;

1. A machine of the class described, comprising a frame, a brushcarrying spindle mounted in thel'frame, a driven member, means for operating the spindle from said member, a pivoted'and spring pressed frame on the first frame, a brush carrying shaft mounted in the free'end of. the pivoted frame, means for operating the last named spindle from the said driven member, and means for engaging the spindle carried by the pivoted frame to render it inactive. V

2. A machine of the class described, comprising a frame, a brush-carrying spindle mounted in the frame, a friction wheel on the spindle, a friction disk with which the friction wheel engages, a pivoted frame mounted on the first frame, a spring having its ends secured to said frames, a brushcarrying spindle mounted in the free end of the pi voted frame, a friction wheel on the spindle and adapted to engage the said friction disk, and means for swinging the pivoted frame to disengagethe friction wheel of the spindle carried thereby from the friction disk. v V

3. A machine of the class described comprising a frame, a pair of spindlesmovable laterally toward and from 7 each other, a driving member, means on the spindles for engaging opposite sides of the member, means for urging the spindles toward each other to hold the means in engagement with the said member, and a cam carried by one of the spindles and movable int-o engage ment with the other spindle for disengaging the said means from the member.

41-. A machine of the class described comprising a mainframe, a rotatable spindle mounted thereon, a secondary frame hingedly connected with the main frame, a rotatable spindle on the secondary frame, a driving element mounted on the main frame, members mounted on the spindles for engaging vopposite sides of the driving element, spring means acting on the frames to hold the said members in engagement with the driving element, a cam pivoted on'the firstmentioned spindle vand engageable with the second-mentionedspindle to move the spindles apart and the'members out of engagement with the said driving-element.

5. The combination of a supporting structure, a pair of spindles mounted thereon, a

friction wheelon each s indle a friction diskdisposed between the wheels,'a shaft onnthe structure for supporting the friction disk, a gear casing mounted on-the structure, a shaft carried by the casing, a crank connectedwith the last-mentioned shaft, a gearing between the shafts, and means for ad justably mounting the casing on the said structure.
